Additional Information:

Description: (OMIM) Fanconi anemia (FA) is a clinically and genetically heterogeneous disorder that causes genomic instability. Characteristic clinical features include developmental abnormalities in major organ systems, early-onset bone marrow failure, and a high predisposition to cancer. The cellular hallmark of ...
Clinical Description OMIM The existence of at least 2 separate loci, homozygosity at either of which can result in the Fanconi syndrome, was indicated by the complementation observed by Zakrzewski and Sperling (1980) in cell hybrid studies. They found no complementation ...
Molecular genetics OMIM In individuals with Fanconi anemia of complementation group B, Meetei et al. (2004) found mutations in the FANCB gene, which they designated FAAP95 (300515.0001-300515.0004). They transfected lymphoblasts from individuals with FA with cDNA encoding FAAP95 and demonstrated that ...
